Below is a zip-file containing  the files required to generate the designs in the Goos & Donev mixture-process variable design paper.

The file spd1.for is simply the Fortran code of the optimal split-plot design construction algorithm by Goos & Vandebroek (2003, Technometrics). The input files that should be used with this program are mpvinput.prn and constrainedmpvinput.prn. These input files will produce the designs in Tables ... and ... of the paper. The file mpvinput.prn contains explanations for constructing a proper input file of your own.

The files spd1center4.for, spd1center8.for and spd1center12.for contain the code for computing the design with 4, 8 and 12 center points in Table . Apart from a few lines in the subrouting gmatri, the code is identical to the one in the file spd1.for. The input files required for computing the Bayesian design are center4mpvinput.prn, center8mpvinput.prn and center12mpvinput.prn. Notice that for these designs, only 6, 5 and 4 whole-plots of 4 runs need to be computed. Consequently, only 24, 20 and 16 runs need to be generated.

The file spd1bayes.for contains the code for computing the Bayesian design in Table . Apart from a single line in the subrouting gmatri, the code is identical to the one in the file spd1.for. The input file required for computing the Bayesian design is bayesianmpvinput.prn. Notice the potential term that is specified in that input file.
